This book addresses Cold War intelligence and counterintelligence in a manner that provides a broad historical perspective and then brings the reader to a never-before documented artifact of Cold War history.The book details the intelligence/counterintelligence dynamic that was among the most emblematic of the Cold War.Ultimately, the book addresses a saga that remains one of the true Cold War enigmas.
